Revision b8f42738acaddf67731c34935c0994e09a588ca7 authored by Michael J. Ruhl on 26 September 2017, 13:06:28 UTC, committed by Doug Ledford on 27 September 2017, 15:10:36 UTC
During base context setup, if setup_base_ctxt() fails, the context is deallocated. This is incorrect because the context is referenced on return, to notify any waiting subcontext. If there are no subcontexts the pointer will be invalid. Reorganize the error path so that deallocate_ctxt() is called after all the possible subcontexts have been notified.
